I do not know whether this is a missing function in Nemo or that my install is busted somehow, but I cannot select any file by dragging with my mouse. Normally while holding down the left button of a mouse while dragging a selection box should appear which you can use to select a/multiple file/files. The selection box DOES appear on my desktop but is does NOT appear in Nemo. If my question is not clear I am referring to the blue selection box in the figure below:

The problem is not theme-related because I have tried a bunch.

My system is running on Linux Mint 13 Cinnamon 64 bit, with backports from Mint 14 enabled (through which I acquired Nemo). Currently installed Nemo version is 1.1.2. Feel free to ask me any system settings questions.

I re-installed Nautilus to check whether it is a Nemo problem. The problem also exists for Nautilus. However I have found out that it works both in Nautilus and Nemo under certain conditions: folder view has to be set to either Icons or Compact. The problems thus only occurs for the List folder view option.
